For test the communication conversion between serial port and network , you should connect the USR-N668 to PC with serial cable(or USB to serial cable),connect the Ethernet port of USR-N668 and PC with network. Make sure the connection is correct , then power on.USR-N668 is an industrial-grade eight-serial port server, which realizes RS232/485/422 to Ethernet two-way transparent transmission function, and can flexibly switch between different serial ports; 2 Ethernet ports, 10/100Mbps rate; Support Modbus TCP to Modbus RTU; Support timeout restart and timeout reconnection; Support remote monitoring and remote firmware upgrade; Support virtual serial port, DNS domain name resolution, external door opener and other functions; Support custom heartbeat package and registration package to eliminate dead links.
